CNN reportedly apologized Friday after one of its producers was overheard joking about President-elect Donald Trump’s plane crashing.

“An unfortunate and inappropriate remark was made by one of our producers off camera yesterday,” a CNN representative told Business Insider in a statement. “We have apologized to the Trump transition team, and the producer has been disciplined.”

A video of the gaffe posted on YouTube showed CNN national correspondent Suzanne Malveaux preparing for a live shot at Carrier’s Indianapolis plant prior to Mr. Trump’s arrival on Thursday.

An unidentified producer was heard off camera discussing various hand signals with Mr. Malveaux.
